VETERINARY IMPREGNATING INSTRUMENT.

To all whom it may concern:

Be it known that I, CHARLES IV. BAIRD, a citizen of the United States,residing at Deep River, in the county of Poweshiek and State of Iowa,have invented a certain new and useful Veterinary ImpregnatingInstrument, of which the following is a specification.

My invention is especially designed for use in connection with so calledbarren mares, that is, to say, mares which are prevented from becomingpregnant for the reason that the neck or mouth of the womb is tightlyclosed, or its outer end is covered by some abnormal growth or in caseswhere the outer end of the mouth of the womb is inclined downwardly orlaterally. In other words, my invention is intended for use in caseswhere there is some slight structural abnormal condition which preventsthe entrance of semen into the womb.

Hy object is to provide an instrument of this class of simple, durableand inexpensive construction, that may be readily, quickly and easilyapplied by persons without special skill and when in position, it willhold the mouth of the womb open, and also hold the mouth of the womb ina straight line with the central portion of the vagina, and also hold toone side any abnormal growths that might otherwise tend to obstruct thepassageway into the womb.

My further object is to provide an instrument of this kind that, afterbeing inserted in proper position, will not in any way interfere withthe act of copulation, and which may be readily and easily removedwithout the use of instruments, after copulation.

My invention consists in the construction of the device, whereby theobjects contemplated are attained, as hereinafter more fully set forth,pointed out in my claims, and illustrated inthe accompanying drawings,in which Figure 1 shows a central longitudinal, sectional, view of thecomplete instrument embodying my invention. Fig. 2 shows a sideelevation of the impregnating tube. Fig. 3 shows a side elevation of thetube inserting device, and Fig. 1 shows a sectional view on the line 1lof Fig. 2.

Referring to the accompanying drawings, I have used the referencenumeral to indicate the body portion of the tube which is Specificationof Letters Patent.

preferably made of soft rubber of such thickness that it will notcollapse and close on account of the pressure to which it will besubjected when in use. At the inner end of the tube is a flange formedon the exterior of the tube, and comprising a number of flexiblesections 11 extended outwardly at right angles to the tube. At the outerend of the tube is a funnel shaped flange 13, the outer edge of which iscurved first away from the tube, and then toward the inner end thereof.An opening 15 is provided in said flange, to receive a cord for thepurpose of removing the instrument.

The tube inserting member comprises a straight round body portion 16having a rounded tapered end 17 and at the other end having an enlargedhead 18, and provided with a handle or knob, 19.

The proportion of the parts is such that when the body of the insertingmember is placed in the tube, it will loosely fit the interior thereof,and the rounded end will project beyond the inner end of the tube, asshown in Fig. 1, so that said tapered end will co-act with the inner endof the tube, in forming a passage way into the mouth of the womb,without injury to the same. The enlarged head at the outer end of theinserting member serves to engage the flange of the outer end of thetube, so that the inserting member may force the tube into position.

In practical use, the inserting member is placed in the tube as shown inFig. l. The operator grasps the tube, and the handle or knob of theinserting member, and then passes it with his hand through the vagina.He then uses the point of the inserting member to form an openingthrough the mouth of the womb, and pushes the instrument into the womb,until the head of the tube stands within the womb. During the insertingmovement, the sections of the flange will fold close to the tube, andthus will not materially obstruct the insertion of the tube. After theflange enters the interior of the womb, it will return to its normalposition, and prevent the withdrawal of the tube, unless great pressureis exerted on it. He then withdraws the inserting member.

The tube performs the double function of providing a passage way intothe womb, and of holding the mouth of the womb in proper position, andalso of holding aside any abnormal growths or tissues that would other-Patented Jan. 11, 1910..

. magma wise obstruct the mouth of the Womb. Hence, when copulationtakes place, semen is injected directly through the tube into the Womb.The tube is afterward removed by pulling upon the cord, and the sectionsof the flange Will then fold toward the inner end of the tube.

I claim as my invention:

1. A device of the class described comprising a flexible tube, and anintegral flange near one end on its exterior, formed of sections dividedradially, for the pur poses stated. v

2. A device of the class described, comprising a tube, and a retainingmember thereon consisting of a flexible flange formed in sectionsdivided radially.
